Has anyone ever had their IP blocked by recaptcha? I've never seen this happen before, but I use private proxies to post to various web 2.0 sites, and the other day I realized that when using some (some, not all) of my private proxies the recaptcha image wasn't being displayed on the web 2.0 registration form anymore. I then went to http://www.google.com/recaptcha/learnmore to see if the recaptcha form would display, and it did not. The following message is displayed: "We're sorry... ... but your computer or network may be sending automated queries. To protect our users, we can't process your request right now." The only thing I have used these private proxies for is scraping Google. I thought maybe my IP was blocked because of scraping, but that would only be a temporary ban. I suppose the person that used the IPs before me could have got them banned. I also waited 48 hours but the ban is still in place. I plan to request that my proxy IPs are replaced, but I'd like to know if anyone else has experienced this and if so what you think may have caused it, I would like to avoid this in the future if possible.
